Transducers with the improved anti-interference ability for automated ship's systems

Abstract

The paper discusses the problem of improving the anti-interference ability of transducers applicable to automated ship’s systems, especially to those of marine engine room. A variety of detection methods and types of sensors for some physical quantities is presented and illustrated by examples. Mechanisms of interference penetration into measuring circuits of automatic control loops and main reasons of disturbing factors generation under ship’s conditions are shortly pointed out. Some methods and technical means to eliminate them, such as a choice of appropriate measurement method, a way of signal processing and also constructional and technological solutions are discussed. Special attention is paid to integrated and smart sensors and their application in ship's hostile environment. Finally, some conditions concerning the use of such transducers in microcomputer monitoring systems are formulated.
